It is rutile base electrode specially de-signed for welding of Super duplex stain- less steels. Which contain 25.5%Cr, 9.5% Ni, 4% Mo & 0.25% N. The deposited weld metal has a duplex microstructure con- sisting of an austenite ferrite matrix, with high ductility and improved resistance to pitting corrosive attack and to stress corrosion cracking. It gives excellent welding characteristic in all position with smooth and stable arc, self lifting slag .the weld bead is smooth, fine rippled and shiny.
It is used for welding of super duplex stainless steel such as SAF 2507,Zeron 100, ferralium 255 , UR47N , DP3 and similar steels.
